Surface of the liver is irregular and its echogenicity is mildly coarse and heterogeneous. Mild ascites is seen around the liver (A, B). Common bile duct and intrahepatic bile duct dilation (C). Sagittal scan of aorta shows stenosis of proximal of celiac trunk (D). The huge aneurysm with “yin and yang” sign on color Doppler ultrasound, and turbulent arterial blood flow on Spectral Doppler (E, H, I). The aneurysm is superiorly connected to superior mesenteric artery. The superior mesenteric artery continues its course on the anterior surface of the aneurysm to supply the small bowel (F, G). Hollow arrows shows superior mesenteric artery, short arrow shows dilated common bile duct, and long arrow shows celiac trunk
